The Ballachulish Bridge is a two-lane steel truss road bridge that carries the A82 trunk road across Loch Leven as shown in Figure 1. Figure 1: Ballachulish Bridge The following maintenance works are proposed to be undertaken on the Ballachulish Bridge over the next five years: Carriageway and footpath resurfacing Bearing Replacement 2 Transport Scotland Trunk Road and Bus Operations Document: ENVIRONMENTAL IMPACTS AND PROPOSED MITIGATION: SUMMARY Issue Baseline Conditions Impact Mitigation Air and Climate There are approximately eight residential properties During the construction phase air quality impacts are likely to stem Plant, machinery and vehicles associated with the works will have engines switched off when not in north-east of the scheme within 200m and five from construction vehicles and plant on-site as well dust as a use in order to minimise emissions: residential properties witin 200m south of the scheme. result of maintenance activites., impacts on air quality are not anticipated to be significant, provided the the Site Environmental Machinery and vehicles will have been serviced regularly; Management Plan (SEMP) is adhered to and mitigation is There is a small industrial estate with four commercial A traffic management plan will be in place to control the length of time that traffic needs to idle; properties north-east of the scheme within 200m of followed. the scheme.

The proposed work is not expected to affect air quality during the operational stage, as it will not result in change in traffic levels or dynamics.
